Both official additions, which were previously reported by MMAjunkie.com (www.mmajunkie.com), take place on the evening’s un-aired preliminary card.

Scanlon (7-0 MMA, 0-0 UFC), who trains with the likes of UFC veterans Terry Etim and Paul Taylor at Liverpool’s Team Kaobon, owns seven stoppages (six in the first round) among his seven career wins. While fighting on the U.K. fight circuit, he’s posted five submissions wins and two TKO victories, though he missed nearly two years (mid-2008 to early 2010) due to injuries. Most recently, he topped Michael Reid (2-1 at the time) with a 10-second head-kick KO.

The ground specialist puts his skills to the test against Krauss (9-0 MMA, 0-0 UFC), who signed a four-fight deal in August and secured a UFC 122 slot. Nicknamed “Panzer,” Krauss trains with Grappling Arts in Freiburg, Germany, and is the welterweight champion of U.K.-based Cage Warriors Fighting Championships promotion. With an unblemished professional record, he has notched all but two of his nine victories via submission.

Matyushenko (24-5 MMA, 5-3 UFC) was originally slated to face Jason Brilz, but Brilz suffered a back injury in training and was forced to withdraw. “The Janitor” attempts to clean up this time around after a quick TKO loss to division golden boy Jon Jones at UFC on Versus 2 in August. It was Matyushenko’s first loss inside the octagon since he began a second stint with the promotion in late 2009 and racked up wins over Igor Pokrajac and Eliot Marshall.

Ferreira (18-6 MMA, 0-0 UFC), a 12-year MMA veteran, is a veteran of Brazil’s old-school bare-knuckle promotion, World Vale Tudo Championship, and currently enjoys a seven-fight win streak. In the WVC, he racked up early career wins over Heath Herring, Bob Schrijber and Moti Horenstein before he took a three-year break from the sport in the early 2000s.

A submission specialist, Ferreira has earned 17 of his wins by way of first-round tapout.
